Saving Configuration Changes

You must enter the copy running-configstartup-configcommand to save your configuration changes to NVRAM, so that the changes are not lost if there is a system reload or power outage. For example:

Router# copy running-config startup-config

It might take a few minutes to save the configuration to nonvolatile random-access memory (NVRAM). After the configuration has been saved, the following message appears:

[OK]

Router#

Where to Go Next

Now that you know some Cisco IOS software basics, you can begin to configure the router by using the CLI.

Remember the following:

•You can use the question mark (?) and arrow keys to help you enter commands.

•Each command mode restricts you to a set of commands. If you have difficulty entering a command, check the prompt and then enter the question mark (?) to see a list of available commands. You might be in the wrong command mode or be using the incorrect syntax.

•To disable a feature, enter the keyword no before the command; for example, no ip routing.

•You need to save your configuration changes to NVRAM so that the changes are not lost if there is a system reload or power outage.

Proceed to Chapter 3, “First-Time Configuration,” for first time configuration. Otherwise, proceed to Chapter 4, “Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line Interface,” to begin configuring the router.
